I am going to put my 90 on a dyno soon... then its on to the mods!
:)

All stock right now, dyno soon.

FastZR1

With a flowmaster cat back, K & N, forced air intake I had 328 SAE corrected on a dynojet on my 91.

Now I am doing a few other things to the car and we'll see in a few months how much more power I can get.

Stock was 326 rwhp.

Ported and polished Plenum, inj, housings, Alspaugh headers, B&B (with resonator), chip tune. Now 370 rwhp.

90 Corvette ZR-1

A friend of mine dynoed his 90 @ 350 hp with only headers, no cats, corsa's on the stock chip this year at bg and it was running rich. The car only has 9k on it.

The Lurker

I only did a bit over 320 at the rear wheels when I was tuning it. I can't wait to get it on the dyno and let the secondaries turn on.

FASTAZU

324rwhp bone stock..
I have added a catback Flowmaster no dyno yet to see what kind of gain...

MrCrowley

I had 434rwhp the last time my car was dynoed. But since then I have done alot more modding. I added the Forced-air system, carbonfiber drive and half shafts for less rotating weight, and an x-pipe. Aaron's 368 added 21rwhp by adding the x-pipe alone! I think I would be somewhere in 440's by now especially with a new clutch.

phrogs

Well I dynoed mine last year and I got 319 hp at the rear wheels,
that was with bad faulty injectors and a colapsing air duct and secondary problems with the low rpm stumbling....

I have replaced the injectors and I have new vacum lines im going to replace and I have a new air duct on the way so ill let you know
what I pull after I get her all fixed im hoping for a lot more!

Holy Sh** Pete sure you dont have a 368 buttoned up under there ??? :eek:
Those are big numbers for a 350 .....thumbs:....


Thanks Tim, i can only wish it's a 368.
I'm trying to get the most out of a 350 i think 470-480rwhp is possible out of a 350 LT5 with maybe siemised plenum, IH's and cams if i had extra $$$ i would be willing to do the R&D.
I would like to buy another plenum & IH's to siemise them and try to get above 450rwhp with the stock cams or like i said before if i can borrow someones siemised plenum & IH's to try them on the dyno,i'd pay shipping.
I know they say it won't work on a stock 350 but i still like to try it for myself
and maybe prove them wrong. :)
The way i ported my heads was out of the norm and it worked out great.
Marc Haibeck is now getting this kind of HP out of 350 LT5's
Soon you will see a lot more 350's making this kind of HP and will probably see an increase in power on 368's and 415's
